JP 2002-231292 A

  However, in a fuel cell module that houses a solid oxide fuel cell that generates power at a high temperature, when air at room temperature is supplied into the fuel cell module by a blower, the temperature in the fuel cell module decreases, and the fuel There was a problem that the power generation efficiency of the battery module was lowered.

  Therefore, an object of the present invention is to provide a fuel cell device capable of supplying high-temperature air into the fuel cell module.

  The fuel cell device of the present invention has a fuel cell module in which a plurality of fuel cells are housed in an outer case having a hollow column, and a blower for supplying air to the fuel cell module, A fuel cell apparatus partitioned into a fuel cell module storage chamber in which the fuel cell module is stored and an auxiliary device storage chamber in which the blower is stored by a partition provided in the outer case, The support column is provided with an air intake opening that opens into the fuel cell module storage chamber, and is provided with a passage that guides air that has flowed into the support column from the air intake port to the blower.

  In such a fuel cell device, the high-temperature radiant heat generated by the power generation of the fuel cell module warms the air in the fuel cell module housing chamber, and the warmed air is supplied from the air intake port provided in the hollow column. It flows into the column. The air flowing into the column from the air intake port flows through the passage leading from the column to the blower and is supplied to the blower and is also supplied from the blower to the fuel cell module. Therefore, it is possible to suppress a decrease in the temperature in the fuel cell module, and it is possible to improve the power generation efficiency of the fuel cell module.

  The fuel cell device according to the present invention further includes a blower air intake pipe constituting at least a part of the passage between the strut and the blower, and the strut and the blower air intake air in the strut. It is preferable that a column partition plate for partitioning the inside of the column is provided in the vicinity of the connection portion with the pipe, and the air intake port, the connection portion, and the column partition plate are positioned in this order.

  In such a fuel cell device, a blower air intake pipe that constitutes a passage for guiding the air flowing into the strut from the strut to the blower is provided between the strut and the blower. A support partition plate for partitioning is provided. Since the air intake, the connecting portion, and the column partition plate are positioned in this order, the air flowing in from the air intake flows only to the column partition plate portion provided in the connecting portion. It circulates in the air intake pipe.

  Moreover, when the connection part is provided in the auxiliary machine storage chamber side, it is possible to shorten the flow path that flows through the column that constitutes the auxiliary machine storage room, thereby suppressing a decrease in temperature. . Thereby, the warmed air can be efficiently supplied to the fuel cell module.

  In the fuel cell device of the present invention, the partition portion is constituted by a partition plate having a cavity portion, and the inside of the column and the cavity portion of the partition plate are communicated with each other, and the cavity portion of the partition plate and the blower are connected. It is preferable that a blower air intake pipe is connected to the passage, and the passage includes the partition plate and the blower air intake pipe.

  In such a fuel cell device, warmed air that circulates inside the support column circulates through the cavity of the partition plate. The air supplied to the cavity of the partition plate is further warmed by radiant heat from the bottom surface of the fuel cell module. The further warmed air is sucked into the blower via the blower air intake pipe and supplied to the fuel cell module.

  In addition, since the air flowing through the cavity of the partition plate is supplied to the fuel cell module by the blower, the temperature of the partition plate can be lowered. Therefore, it is possible to suppress the radiant heat generated by the power generation of the fuel cell module from being transferred to the accessory storage chamber, and it is possible to prevent a failure due to the heat of the accessory.

  Further, in the fuel cell device of the present invention, the air flow rate adjusting means is connected in the middle of the passage, and the air flow rate adjustment is performed so that the temperature of the air sucked by the blower becomes a predetermined temperature.

By controlling the above, it is possible to improve the durability of the blower, and to improve the power generation efficiency of the fuel cell module by supplying air at a predetermined temperature to the fuel cell module.

  In the fuel cell device of the present invention, the air heated by the radiant heat generated by the power generation of the fuel cell module is guided to the blower and supplied to the fuel cell module by the blower, so that the temperature of the fuel cell module decreases. This can suppress the power generation efficiency of the fuel cell module.

The electric power generated by the fuel cell 101 is converted into AC power by the power conditioner 112 and then supplied to an external load.

  In FIG. 1, a broken line indicates a main signal line transmitted to the control device 114 or a main signal path transmitted from the control device 114, and arrows indicate oxygen-containing gas, fuel, water, exhaust gas, etc. The flow direction is shown.

  Here, each member constituting the power generation unit is housed in an outer case to constitute a fuel cell device. Hereinafter, the fuel cell device of the present invention will be described.

  FIG. 2 is a schematic view schematically showing the fuel cell device 1 of the present invention, and FIG. 3 is an exploded perspective view thereof. In FIG. 3, some members are omitted. In the following drawings, the same number is assigned to the same member. In addition, the broken line in the figure has shown the main signal path | route transmitted from the control part mentioned later or the main signal path | route transmitted from a control part. The arrows indicate the flow of air (oxygen-containing gas), and the broken-line arrows indicate the flow of exhaust gas generated by the power generation of the fuel cell module.

  In FIG. 2, the fuel cell device 1 is a fuel cell module in which a fuel cell module 3 (hereinafter abbreviated as a module) in which a plurality of fuel cells are housed is disposed in an outer case 2 having a hollow column 8. A storage chamber 4 (hereinafter abbreviated as a module storage chamber), and an accessory storage chamber 6 in which a blower (blower) 5 serving as means for supplying air (oxygen-containing gas) to the module 3 is disposed below, The module storage chamber 4 and the supplementary storage chamber 5 are partitioned vertically by a partition portion 7 disposed in the outer case 2. In addition, the partition part 7 should just partition the module storage chamber 4 and the auxiliary machinery storage chamber 5, and the module storage chamber 4 and the auxiliary machinery storage chamber 5 may be partitioned with the clearance gap. Moreover, as the partition part 7, a plate-shaped partition plate can be used, for example, and it demonstrates as the partition plate 7 in the following description.

  Further, in FIG. 2, in order to increase the strength of the outer case 2, hollow support columns 8 are provided that stand in the height direction of the outer case 2. Although FIG. 3 shows an example in which a total of four support columns 8 are provided at each corner of the exterior case 2, the number can be appropriately increased or decreased according to the size, weight, etc. of the exterior case 2. 2 and 3 show the case where the support column is erected in the height direction of the exterior case 2, it can be provided in the width direction or the depth direction of the exterior case, for example. 2 and 3, the support column 8 is provided without communicating with the partition plate 7.

  Further, in FIG. 2, in the auxiliary machine storage chamber 6, a control device 12 that controls the blower 5, a heat exchanger 13 that collects exhaust heat from the exhaust gas of the module 3, and exchanges heat with the water circulating inside, An exhaust pipe 14 for exhausting the exhaust gas after recovering heat to the outside of the outer case 2 is provided. Here, the blower 5 and the support column 8 are connected by a blower air intake pipe 10, and the blower 5 sucks the air flowing through the support column 8 and supplies it to the module 3, which will be described in detail later. To do.

  By the way, when the fuel cell housed in the module 3 is a solid oxide fuel cell that generates power at a high temperature, when the air at room temperature in the auxiliary equipment storage chamber 6 is supplied into the module 3 by the blower 5, There is a possibility that the temperature in the module 3 is lowered and the power generation efficiency of the module 3 is lowered. Therefore, the air supplied into the module 3 by the blower 5 is preferably heated (warmed) before being supplied to the module 3.

  In addition, when the fuel cell housed in the module 3 is a solid oxide fuel cell that generates power at a high temperature, the high-temperature heat generated by the power generation of the module 3 is thermally diffused as radiant heat, and the module storage chamber There is a possibility that the temperature of 4 becomes high, and consequently the temperature of the outer case 2 becomes high. Therefore, it is preferable that the temperature of the outer case 2 can be prevented (suppressed) from becoming high.

  Here, in the fuel cell device of the present invention, a passage for supplying the air flowing into the support column 8 provided in the exterior case 2 to the blower 5, that is, a passage for supplying the air in the module storage chamber 4 to the blower 5 is provided. Have.

  In the fuel cell device shown in FIG. 2, the radiant heat of the module 3 is effectively used to supply the air warmed into the module 3 by the blower 5 and the temperature of the outer case 2 is prevented from becoming high. Therefore, an air intake 9 that opens to the module storage chamber 4 is provided at the top of the support column 8.

  In such a structure, the air in the module storage chamber 4 heated by the radiant heat generated by the power generation of the module 3 is taken into the column 8 from the air intake 9 and the air flowing into the column 8 is converted into the column 8. Then, the air guided to the blower 5 through the blower air intake pipe 10 connecting the support column 8 and the blower 5 is supplied into the module 3. That is, in FIG. 2, the passage for supplying the air in the module housing chamber 4 to the blower 5 is formed by the air intake port 9, the column 8 and the blower air intake pipe 10, and the air flowing into the column 8 is supplied from the column 8 to the blower. The passage to be formed is formed by a blower air intake pipe 10.

  And since the warmed air which distribute | circulates the inside of the support | pillar 8 is supplied to the module 3, it can suppress that the temperature in the module 3 falls, and can improve the power generation efficiency of the module 3.

  In addition, since the blower 5 inhales the air heated by the radiant heat generated by the power generation of the module 3, an amount of air corresponding to the air circulating in the support column 8 (outside air at normal temperature) enters the module storage chamber 4. In this way, the temperature in the module storage chamber 4 can be lowered. Therefore, it is possible to suppress the temperature of the outer case 2 from being increased due to the radiant heat generated by the power generation of the module 3, and it is not necessary to provide a heat insulating material inside the outer case 2 or a heat insulating material provided inside the outer case 2. The amount can be reduced.

  In FIG. 2, the supply method of the outside air taken into the module storage chamber 4 is omitted. However, for example, the air (room temperature) in the auxiliary machine storage chamber 6 provided with the outside air inlet in the exterior case 2 is used as the module storage chamber 4. For example, air can be supplied to the module storage chamber 4 by supplying to the module storage chamber 4. In this case, in order to efficiently warm the air supplied to the module housing chamber 4, for example, the outside air inlet is preferably provided at a position opposite to the support column 8 through which the warmed air flows.

  When the radiant heat from the module 3 becomes particularly high, a heat insulating material can be attached to the module 3 to lower the temperature of the radiant heat so that the outer case 2 does not become particularly high.

  FIG. 4 is a schematic view showing another example of the fuel cell device of the present invention. At least a part of a passage through which the support column 8 and the blower 5 supply air flowing into the support column 8 from the support column 8 to the blower 5 is shown. The blower air intake pipe 10 is connected. Further, in this column 8, a column partition plate 15 for partitioning the inside of the column 8 is provided in the vicinity of the connecting portion 11 between the column 8 and the blower air intake pipe 10, and the column 8 (FIG. 4). In this case, the air intake 9, the connecting portion 11, and the support partition plate 15 are arranged in this order. In FIG. 4, the connecting portion 11 is provided on the support column 8 constituting the auxiliary machine storage chamber 6. In FIG. 4, the passage for guiding the air flowing into the column 8 to the blower 5 is formed by the air intake port 9, the column 8, and the blower air intake pipe 10.

  For example, when the warmed air in the module storage chamber 4 is efficiently circulated to the blower air intake pipe 10, the air flowing into the column 8 from the air intake 9 and flowing inside the column 8 is It is preferable to circulate to the vicinity of the connection part 11 with the blower air intake pipe 10 and to circulate from the connection part 11 to the blower air intake pipe 10.

  Further, in FIG. 4, since the connecting portion 11 is provided in the column portion that constitutes the auxiliary machine storage chamber 6, it flows into the column 8 from the air intake 9 and flows through the column 8. In particular, the temperature of the air heated in the module storage chamber 4 may decrease during the flow through the inside of the column 8 positioned in the auxiliary device storage chamber 6.

  Here, in FIG. 4, the inside of the support column 8 is partitioned in the support column 8 below the connection portion 11 between the support column 8 and the blower air intake pipe 10 and in the vicinity of the connection portion 11 (in FIG. 4). By providing a column partition plate 15 for dividing the column vertically (that is, the air intake 9, the connecting portion 11, and the column partition plate 15 are positioned in this order), the air flows from the air intake 9 into the column 8. Thus, the air flowing through the column 8 is prevented from flowing downward from the column partition plate 15. Thereby, the air warmed in the module housing chamber 4 can be efficiently circulated from the connecting portion 11 to the blower air intake pipe 10 and can be supplied to the module 3 together.

  FIG. 5 is an exploded perspective view showing another example of the fuel cell device of the present invention. Air warmed in the module storage chamber 4 that circulates inside the plurality of support columns 8 is sucked by the blower 5, An example of supply to the module 3 is shown.

  In order to efficiently supply the air warmed in the module housing chamber 4 to the module 3, it is preferable to supply the air flowing through the plurality of columns 8 to the blower 5. Here, it may be difficult to connect the plurality of struts 8 and the blower 5 due to the structure of the blower, and a large number of blower air intake pipes 10 for connecting the plurality of struts 8 and the blower 5 are required. Therefore, the fuel cell device may be increased in size.

  Therefore, in FIG. 5, the partition portion is configured by the partition plate 7 having a hollow portion, and the inside of the support column 8 and the hollow portion of the partition plate 7 are communicated. As a result, the air that has flowed into the support column 8 from the air intake port 9 of the support column 8 circulates in the support column 8, and then is partitioned by the communication portion 16 that connects the interior of the support column 8 and the cavity of the partition plate 7. It circulates in the cavity of the plate 7. The air flowing through the hollow portion of the partition plate 7 flows through the blower air intake pipe 17 that connects the hollow portion of the partition plate 7 and the blower 5 and is sucked by the blower 5 and then supplied to the module 3. As a result, the air flowing through the plurality of struts 8 can be efficiently supplied to the module 3, and it is not necessary to directly connect each of the plurality of struts 8 and the blower 5. An increase in size can be suppressed. In FIG. 5, the passage for supplying the air in the module storage chamber 4 to the blower 5 is formed by the air intake port 9, the support column 8, the communication portion 16, the cavity of the partition plate 7, and the blower air intake pipe 17. The passage for supplying the air flowing into the blower 8 from the support column 8 to the blower is formed by the communication portion 16, the cavity portion of the partition plate 7, and the blower air intake pipe 17.

  Further, the warmed air that circulates inside the support column 8 is further heated by the radiant heat from the bottom surface of the module 3 in the process of flowing through the hollow portion of the partition plate 7, and circulates through the blower air intake pipe 17. Therefore, the temperature in the module 3 can be prevented from decreasing, and the power generation efficiency of the module 3 can be improved.

  In addition, since the warmed air flowing through the cavity of the partition plate 7 is supplied to the module 3, the temperature of the partition plate 7 can be lowered, and the radiant heat generated by the power generation of the module 3 is stored in the auxiliary machine. It is possible to suppress heat transfer to the chamber 6 and to suppress (prevent) failure or the like due to heat of the auxiliary machine.

  FIG. 6 is an exploded perspective view showing another example of the fuel cell device of the present invention, and FIG. 7 is a schematic view of the fuel cell device shown in FIG. In FIG. 6, some members are omitted. The fuel cell device 41 shown in FIG. 6 is an example in which the support columns 8 are provided in the width direction and the depth direction of the outer case 2 in addition to the height direction of the outer case 2. In FIG. 6, the support column 8 provided in the width direction and the depth direction of the exterior case 2 is provided so as to communicate with the upper end portion of the support column 8 provided in the height direction of the exterior case 2. An example is shown. In the description after FIG. 6, for the sake of convenience, the support column 8 provided to communicate the support columns 8 provided in the height direction is referred to as a column 18.

  For example, when the weight of the module 3 is heavy, the strength of the fuel cell device (exterior case 2) may be weak just by standing the plurality of support columns 8 in the height direction of the external case 2. Therefore, in FIG. 6, the strength of the fuel cell device (exterior case 2) can be increased by providing a column 18 and connecting the plurality of columns 8 together.

  Here, the column 18 can be hollow and disposed so that the column 8 and the column 18 communicate with each other, and the column 18 can be provided with an air intake 19 that opens into the module storage chamber 4. Thereby, the air warmed in the module storage chamber 4 circulates in the column 18 from the air intake 19. The air that flows through the inside of the column 18 continues to flow through the column 8, and further flows from the communication part 16 to the cavity of the partition plate 7. The air flowing through the hollow portion of the partition plate 7 flows through the hollow portion air intake pipe 17 and is sucked by the blower 5 and then supplied to the module 3. Therefore, the air warmed in the module storage chamber 4 can be efficiently supplied to the module 3. In FIG. 6, the passages for supplying the air in the module storage chamber 4 to the blower 5 are the air intake 19, the column 18, the column 8, the communication part 16, the cavity of the partition plate 7 and the blower air intake pipe. The passage that is formed by 17 and supplies the air that has flowed into the support column 8 from the support column 8 to the blower is formed by the communication portion 16, the cavity of the partition plate 7, and the blower air intake pipe 17.

  In addition, the air heated in the module storage chamber 4 circulates through the column 18, the column 8, the communication portion 16, the cavity of the partition plate 7, and the blower air intake pipe 17, and is supplied to the module 3 by the blower 5. Thus, the temperature in the module 3 can be prevented from decreasing, and the power generation efficiency of the module 3 can be improved.

  FIG. 8 shows another example of the fuel cell according to the present invention, which shows a fuel cell device 51 that adjusts the temperature of the air flowing through the inside of the support column 8 and through the cavity of the partition plate 7 and supplies it to the module 3. It is.

  In order for the module 3 to generate power efficiently, the heated air flowing through the inside of the support column 8 and the hollow portion of the partition plate 7 is sucked by the blower 5 and then supplied into the module 3. However, when the temperature is high, such as 50 ° C. to 70 ° C., the durability of the blower 5 may be adversely affected and the life of the blower 5 may be shortened. Therefore, although it depends on the type of the blower 5, after the warmed air is adjusted to a predetermined temperature (temperature lower than 50 ° C. to 70 ° C.), the blower 5 sucks and supplies the air into the module 3. It is preferable to do.

  Therefore, in the fuel cell device 51, the air flow rate adjusting means 23 is connected in the middle of the passage for guiding the air flowing inside the support column 8 to the blower 5, and this air flow rate adjusting means 23 is adjusted, Control is performed by the control device 13 so that the temperature of the air taken in by the blower 5 becomes a predetermined temperature set in advance.

  Here, in FIG. 8, the air flow rate adjusting means 22 is connected to the blower air intake pipe 17, and the accessory storage chamber air intake pipe 20 is connected to the air flow rate adjusting means 22. The flow rate of air flowing through the blower air intake pipe 17 and the auxiliary equipment storage chamber intake / intake pipe 20 is adjusted so that the temperature of the air sucked by the blower 5 becomes a predetermined temperature set in advance. Is controlled and adjusted by the control device 12.

  Specifically, in FIG. 8, the temperature of the air sucked through the blower air intake pipe 17 is measured by the temperature sensor 23, and the measured temperature information is transmitted to the control device 12. When the transmitted temperature information exceeds a predetermined temperature set in advance, the control device 12 uses a blower so that the temperature information measured by the temperature sensor 23 becomes a predetermined temperature for the air adjusting means 22. A signal for adjusting the amount of air taken in through the air intake pipe 17 and the amount of air taken in through the auxiliary equipment storage chamber air intake pipe 20 is transmitted.

  Thereby, since the temperature of the air supplied to the module 3 by the blower 5 can be made lower than the temperature that adversely affects the blower 5, the durability of the blower 5 can be improved, and a predetermined By supplying the temperature air to the module 3, the power generation efficiency of the module 3 can be improved. As the air flow rate adjusting means 22, an air flow rate adjusting valve or the like can be used.
